Begun last year, the first round of residential clean-ups targeted the 219 properties found within the original Northern and Southern Assessment Areas — areas straddling Boyle Heights, East L.A., and Maywood that air modeling determined would be most likely affected by Exide’s lead emissions (outlined in light blue, above). More than 10,000 tons of contaminated soil was ultimately removed from a total of 186 properties.

Only 146 properties in the Expanded Assessment Areas have been tested thus far, with 50 being prioritized for immediate clean-up. And while 2,800 letters have been sent out to residences within the expanded areas, it is not clear what the timeline will be for following up on those letters and getting properties tested and/or cleaned. Nor is it clear when DTSC will have sufficient funds to perform a wider clean-up.

Per an order, Exide is on the hook for cleaning up any home where lead levels exceed 400 parts per million and homes with bare soil where levels exceed 80 parts per million (the level at which the state recommends further health screenings). But the settlement reached last November initially set aside just $9 million for residential clean-ups. As clean-ups cost about $40,000 per property, those funds only cover approximately 225 sites. And, as of the end of October, DTSC had already used up $8 million of those funds. DTSC was able to secure an additional $5 million from Exide earlier this spring and $7 million in emergency funds from the state in August. But those funds are nowhere near enough to cover testing and clean-ups in the much wider range of territory Exide is thought to have contaminated.

In an effort to allay some of these fears and promote greater transparency, DTSC has drafted a community engagement plan and meets regularly with an advisory group comprised of community members and advocates and representatives of elected officials and relevant government agencies. It also released the Interim Remedial Measures Work Plan, which offers a detailed discussion of how contaminated soil from the 50 yards prioritized for clean-ups will be safely removed and trucked to distant landfills over the next six months.

The 264-page Closure Plan — needed to ensure health and safety will be protected before the dismantling and decontamination can begin at the 15-acre site — is a very long time coming. [See the Executive Summary, here, appendices, here.]

An earlier version of the draft, submitted in May of this year, was returned to Exide with 82 pages of comments. The weighty Notice of Deficiency signaled a clear disappointment in Exide’s carelessness and inattention to detail. Exide was slammed for not having a proper Executive Summary, not knowing which regulations it was being asked to act in accordance with (and which ones were non-existent), not seeming to know it had to adhere to closure performance standards (not just meet clean-up levels), not creating plans for the movement of slag, the dismantling of the Finished Lead Building, or for assessing/removing the soil contamination once particular sites were dismantled, and not having “any discussion on oversight for closure activities at the facility….an organizational plan for who will provide oversight [or] how oversight will be conducted.” And those were the comments from just one senior engineer in the Hazardous Waste Management Program at DTSC.

Other DTSC specialists harped on Exide’s lack of attention to the methods it would use to clean up contaminated elements of the facility or address ongoing issues, like leaks of contaminated water. Exide apparently also received a host of critiques from the Air Quality Management District in June (which also sued Exide for $80 million in damages for transporting lead chips in leaky trucks), and did not submit a revised draft Closure Plan until July 28.

The July draft was apparently suitable enough, as DTSC drew up the DEIR to examine the potential environmental impacts the closure activities outlined in the plan might have. The DEIR does list some potential revisions for the plan. One major issue involves seven kettles containing more than 12 tons of lead in them. Cranes can be used to remove kettles with less than 12 tons of lead, but those holding more must be moved some other way. In the Closure Plan, Exide suggests re-firing and melting the lead, as that requires the least time and manpower. In the DEIR, concerned about potential emissions, DTSC contemplates cutting the lead up with water or air jets, and explores the subsequent environmental consequences of each.

Other issues raised in the DEIR include the request that Exide replace the current topographic map with a new survey to show all of the changes made at the facility since 2006, alter its truck routes, make modifications to the stormwater system deconstruction process, plan for having to construct an on-site landfill to be able to cap waste there, and perform a site-wide Health Risk Assessment to evaluate the harm the cleaned site might pose and mitigating measures that can be taken (once the first phase of the closure is complete).

Exide has already downplayed their responsibility for lead contamination in the areas surrounding the Vernon plant. An Exide-sponsored study of soil lead concentrations published this summer declared that, beyond the footprint of the facility, “Exide’s estimated contributions to soil lead concentrations are no longer statistically distinguishable from [existing] background concentrations.”

In layman’s terms, that essentially translates to, “Good luck in trying to hold us accountable.”

Once input has been heard from the community, the AQMD, and the City of Vernon and the Closure Plan has been approved by DTSC, Exide will have 30 days to begin work on Phase I of the plan.

According to the timeline found in the Closure Plan (above), Exide estimates that it will take them 5.75 years to dismantle and dispose of the existing facility (an estimate that stands in contrast to DTSC’s projections in the DEIR that it should take 19 – 24 months). A shorter timeline, Exide posits, would make it impossible for them to “complete inventory removal and unit decontamination in an environmentally responsible manner.”

Phase II, entailing the sampling and clean-up of the soil and groundwater beneath the site, was originally projected to be finished in June of 2020. Exide now suggests that it will not even begin planning for Phase II until 2021 (when it will submit a Contingent Closure Plan to DTSC for approval) and that the site clean-up will likely not be complete until 2024. Phase III, listed in an AQMD document as “ongoing” long-term closure, inspection, monitoring, and maintenance activities at the site, is expected to last nearly 30 years, continuing into 2053.
